Bacillus anthracis. click to view larger. Anthrax is the preferred biological warfare agent. It is highly lethal. â¢ 100 million lethal doses per gram of anthrax material (100,000 times deadlier than the deadliest chemical warfare agent). â¢ Silent, invisible killer. â¢ Inhalational anthrax is virtually always fatal.
Figure 1. Electron micrograph of the anthrax causing bacteria, Bacillus anthracis. Anthrax toxin is a three-protein exotoxin secreted by virulent strains of the bacterium, Bacillus anthracis âthe causative agent of anthrax.The toxin was first discovered by Harry Smith in 1954.Anthrax toxin is composed of a cell-binding protein, known as protective antigen (PA), and two enzyme components, called edema factor (EF) and lethal factor (LF). These three protein components act together to impart their physiological effects.nterestingly, each individual anthrax toxin protein is, in fact, nontoxic. Toxic symptoms are not observed when these proteins are injected individually into laboratory animals. However, the co-injection of PA and EF causes edema, and the co-injection of PA and LF is lethal.
